Nobody knows more about efficient packing than people who travel for a living. HuffPost asked a variety of road-focused workers, from business consultants to flight attendants, for the one trick they swear by for an efficiently packed suitcase. Their responses reflect organization at its finest:

4. “I live by rolling my clothes! That way nothing gets wrinkled or lines at the sides.” ― Sarah Williams, senior consultant at Deloitte

5. “Pack all socks and undergarments into a small, reusable cloth bag. Your suitcase will look much more organized even after a few days of halfhearted packing.” ― Alex Reynolds, travel blogger at Lost With Purpose

8. “My latest hack: lightweight black shoes that also work well in the gym, so I don’t have to worry about squeezing in sneakers, too.” ― Zach Honig, editor-at-large of The Points Guy

9. “Pack fragile or valuable things in clothes. Socks within socks make an excellent travel case for microphones.” ― James Lanman, musician

10. ”[I put] toiletries and a change or two of clothes in my carry-on. Nothing’s worse than showing up in another country, finding your bag is lost, and then realizing you’re stuck wearing the clothes you’ve been traveling in for the foreseeable future.” ― Scott Keyes, founder of Scott’s Cheap Flights

12. “Pick shoes that can be worn with multiple outfits so you only have to bring a couple pairs for your trip. And wear one pair on the plane if you can.” ― Alice Cope, former advisory consultant at EY

14. “I love the Away luggage company ― they have small bags that fit into your luggage for the best organization possible. I’m able to plan out my outfits and put them together and know exactly where everything is.” ― Ashley Streff, photographer
